Abstract :
This paper presents a fuzzy logic controlled single-stage power converter (SSC) for photovoltaic powered lighting system (PPLS) applications. The SSC is the integration of a bidirectional buck-boost charger/discharger and a class-D series resonant parallel loaded inverter. The designed fuzzy logic controller (FLC) can control both the charging and discharging current, and improve its dynamic and steady state performance. Furthermore, a maximum power point tracking (MPPT) scheme based on a perturb-and-observe method is also realized to effectively draw power from photovoltaic arrays. Both of the FLC and the MPPT are implemented on a single-chip microprocessor. Simulated and experimental results obtained from the proposed circuit with an FLC have verified the adaptivity, robustness and feasibility
